Abstract

The invention relates to a sound barrier structure for high speed railways. The sound barrier structure comprises a steel upright post and a plurality of sound barrier absorption / sound insulation unit plates which are transversely inserted in the steel upright post; elastic rubber is filled in a gap between a flange plate of the steel upright post and the sound barrier absorption / sound insulation unit plate; the sound barrier absorption / sound insulation unit plate comprises a front side plate, a rear side plate, locking buckles, a central framework and a sound absorption material, wherein the front side plate and the rear side plate are locked to a first locking plate and a second locking plate and the upper side and lower side of the central framework through the locking buckles; and the sound absorption material is filled in the gaps inside the locked front and rear side plates. Based on the conventional sound barriers, the sound barrier structure has good economic performance and durability by improving and expanding the types of the conventional sound barriers, and particularly the mechanical strength is greatly improved; and because the technology of bolt-free connection is adopted, the rigidity, shock resistance, fatigue resistance and safety performance of the sound barrier structure are greatly improved.

Description

Technical field: [0001] The invention relates to the technical field of sound insulation, in particular to a high-speed railway sound barrier structure. Background technique: [0002] With the rapid development of rail transportation, the problem of railway noise pollution is becoming increasingly serious. In order to build an environmentally friendly green railway and reduce the impact of noise on surrounding residents, a certain number of sound barriers are often set up on both sides of the railway, which can hinder the sound from the train from reaching the residents, thereby achieving noise reduction. Therefore, the use of sound barriers has become an effective measure to prevent noise pollution along railway lines. Since the sound barrier is set close to the train track and the train runs at a high speed, the air will be compressed and expanded when the train passes through the sound barrier, resulting in serious air pulsation pressure, which will lead to the destructi...
